1. Select a low slope roof treatment for the upper roof of the Keystone project and incorporate your choice into your 3D architectural model. Do not include structural support of the roof at this time.
Research low-slope roof treatments and walking surfaces that would allow human traffic. Document two products that could be used as a walking surface on the green roof planned for the lower roof of the Keystone Library. Include sketches or images of each product.
A type of low sloping roof consists of a continuous membrane surface and ply wood which brings balance and strength to the project roof.
Another product could be a Bakor Low Slope which has a self adhering SBS which brings longevity to the roof project.
2. Research green roofs and document at least two green roof systems that could be used on the lower roof of the Keystone Library. Select a green roof system for use on the Keystone Library Renovation. Document your selection with a sketch or image of a cross section or of the selected system and label each required layer. Justify your choice.
The below picture is a 5-Boro complex which consists of a garden on type which brings life to the walk on roof and meets green roof requirements.
Intensive systems are deeper in soil depth and are capable of sustaining heavier rooted plants.
